Galvanometer Cables And Connections; Galvanometer Coil Connector (Main Board - J6) - Nutfield Technology QuantumDrive 4000 Manual

7.5 Galvanometer Cables and Connections

Each galvanometer requires two cables for connection to the servo driver board. One
cable provides current to the drive coil (stator). The other cable provides power to the
position detector circuit and communicates the return position signal to the servo. The
two cables are shielded and separated to prevent coupling of the drive signal into the
position feedback signal.

7.5.1 Galvanometer Coil Connector (Main Board - J6)

The mating connector is a Molex 50-57-9403 connector with (3) Molex 16-02-0082
or 16-02-0097 pins. The pins should be used with AWG 24–30 wire.
The galvanometer drive coil connector (J6) receives the galvanometer drive cable. The
drive cable connects between (J6) on the servo driver board and the drive coil connector
on the galvanometer. There are two conductors and a shield that terminates to a floating
terminal inside the galvanometer.
